Some FG users are very interested in seeing how FlightGear runs on lower end/embedded hardware (think RPi-style) using {{Wikipedia|OpenGL ES}}. | Some FG users are very interested in seeing how FlightGear runs on lower end/embedded hardware (think RPi-style) using {{Wikipedia|OpenGL ES}}. | ||
The bigger issue here is we need to ditch PUI (which is in progress) and some OpenGL 1.0 code (HUD, 2D panels especially - can be #ifdef for now) so we can enable Core profile on Mac - since Mac 4.x support (we only hit about 4.3 alas, but with some extensions to get in sight of 4.5) is Core profile only, no Compatability mode. | |||
I *believe* the new open-source Intel-Mesa drivers on Linux (which are supposed to decent quality, and even fast) might be in the same situation.<ref>https://sourceforge.net/p/flightgear/mailman/message/36341578/</ref> | |||
Probably to do it initially, GLES1 would have to be used - I think GLES2 has no fixed function - and simgear/flightgear would have to be patched to use only OSG calls (if possible), e.g. by excluding features/subsystems that still use legacy OpenGL code incompatible with GLES. | Probably to do it initially, GLES1 would have to be used - I think GLES2 has no fixed function - and simgear/flightgear would have to be patched to use only OSG calls (if possible), e.g. by excluding features/subsystems that still use legacy OpenGL code incompatible with GLES. |
